- a deposition of the aforedescribed composition can be obtained by means of arc-welding with coated electrodes, welding by means of a shielding gas or a covered are and a blank metal electrode, respectively, a corresponding filler wire, without preheating of the parts to be welded.
- the invention is not only concerned with the actual alloying material that is deposited on the article to be welded, but also with the material used for welding, for example, the composition of the metal electrodes used in the welding process.
- the welding material used for producing the deposition on the welded seam of articles consisting of high-strength low-temperature steel, in particular steel containing about 9% nickel should have the following composition: traces to 0.2% of carbon in dissolved form, that is, as graphite, Le. a ferrous alloy or a carbide, 5-30% of Cr, 530% of Ni, 6-60% of Co, traces to 12% of Mn, traces to 3.5% of Mo, and 5-15% of W if required, the remainder iron and the unavoidable impurities.
